Study of Energy Optimization Technical Program of Zhao II Oil Transfer Station Gathering and Transportation System
The block within the jurisdiction of Zhao II oil transfer station in Daqing Oilfield is low permeability area. The wells are in condition of low liquid production, high water cut, low temperature environment and poor geological. So a high energy consumption of oil gathering is caused. In order to save the energy, the energy balance model of Zhao II oil transfer station gathering and transportation system was established. Combining with production data, the energy consumption proportion and the main problems were analyzed. And the corresponding optimization programs were proposed. The results showed that Zhao II oil transfer station was expected to conserve 48.97m3/h natural gas and 47.2kW·h/h electricity after optimization. Energy efficiency of station increased 1.32%.The energy-saving effect was significant.
